The most common neuroendocrine tumor is known as a carcinoid tumor. This type of tumor originates from small cells in the neuroendocrine system, which is the body’s network of hormone-producing cells and tissues. Carcinoid tumors tend to arise from cells in the digestive system, including the bronchial tubes, pancreas, and small intestine. These tumors can also be found in the appendix, ovaries, and thymus.
Carcinoid tumors can be benign (non-cancerous) or malignant (cancerous). Benign tumors tend to grow more slowly and are less likely to spread to other parts of the body, while malignant tumors can spread to other organs and tissues, and may be more aggressive.
Carcinoid tumors can cause a variety of symptoms, depending on the size and location of the tumor. Common symptoms include abdominal pain, diarrhea, weight loss, flushing of the skin, wheezing, and shortness of breath. Treatment options depend on the size and stage of the tumor, but may include surgery, chemotherapy, and radiation. In some cases, hormone therapy or targeted therapies may be used.
Though carcinoid tumors are less common than other types of cancer, it is important to be aware of the signs and symptoms. If you are experiencing any of the above symptoms, it is important to see your doctor for a proper diagnosis and treatment plan.
